Abstract
The invention provides a power supply method for an equipment cabinet, which comprises the following power supplying steps: firstly, the equipment cabinet adopts a 220 V commercial power as a power supply input, a power supply module is mounted at the middle part of the equipment cabinet, and the switch of 220 V alternate current to 48 V direct current is realized through an AC (alternate current)/DC(direct current) convertor; the power supply module is connected with a copper bar through screws, and the copper bar adopts 48 V direct current to supply power; nodes needed to be supplied with power in the equipment cabinet can be directly inserted in the copper bar through power supply terminals to get power. Compared with the prior art, the power supply method for the equipment cabinet can further lower the system energy consumption, is low in carbon and environment-friendly, reduces the power waste, lowers the production cost, and is strong in practicability and easy to popularize.
Description
Technical field
The present invention relates to the computer power supply technical field, specifically a kind of rack method of supplying power to that reduces the cabinet system conduction loss.
Background technology
Along with the range of application of internet constantly enlarges, the many business on people's Working Life are the development trend of presentation information all.Calculated performance requirement to the webserver is increasing, and various highdensity rack server systems are also come out one after another.This class server cabinet is to be made of many computing nodes and relevant administrative unit and monitoring unit.Under the scheduling of administrative unit, realize the scheduling of resource to all computing nodes of rack cabinet system, realize the maximization of system-computed ability.Because rack rack computing node deployment density is very high, when the user moves concrete application, load become very large after, it is very high that the power consumption of whole rack can become.According to the rack of 1 46U, the computing node of disposing 40 1U calculates, and for a data center that holds 1000 racks, individual node whenever saves 1W, and whole data center just can save in 1 year: 350,000 degree electricity.Therefore, for telecom operators or Internet user, the electricity charge are very large expenditures.In order to reduce the power consumption in the rack, this paper has proposed a kind of method of supplying power to that reduces the cabinet system conduction loss.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of method of supplying power to that reduces the rack of the loss that electric current produces by improving supply voltage in conduction is provided.
Technical scheme of the present invention realizes in the following manner, the method for supplying power to of this a kind of rack, and its step of specifically powering is:
The first step, at first rack adopts the 220V civil power as the power supply input, and the power supply module is installed in the middle part of rack, realizes realizing that by the AC/DC converter 220V alternating current is to the galvanic conversion of 48V;
Second step, the power supply module is connected by screw with copper bar, this copper bar is 48V direct current supply copper bar;
Each node that need to power in the 3rd step, the rack directly is plugged on power taking on the copper bar by power supply terminal.
The built-in PFC boost converter of described AC/DC converter and DC/DC modular converter, its voltage transitions process is: the 220V civil power is converted to the 380V direct current by rectification, PFC boost converter, and then the 380V direct current is converted to the 48V direct current by the DC/DC modular converter again.
What described power supply module adopted is that efficient is at least 94% power supply module, and what this power supply module adopted is the N+N Redundancy power supply.
The beneficial effect that the present invention compared with prior art produces is:
The method of supplying power to of a kind of rack of the present invention reduces the loss that electric current produces by improving the voltage on the power supply busbar in conduction, further reduce system energy consumption, low-carbon environment-friendly, and minimization waste reduces production costs, and is practical, is easy to promote.

Second step, the power supply module is connected by screw with copper bar, this copper bar is 48V direct current supply copper bar;
Each node that need to power in the 3rd step, the rack directly is plugged on power taking on the copper bar by power supply terminal.
The built-in PFC boost converter of described AC/DC converter and DC/DC modular converter, its voltage transitions process is: the 220V civil power is converted to the 380V direct current by rectification, PFC boost converter, and then the 380V direct current is converted to the 48V direct current by the DC/DC modular converter again.
What described power supply module adopted is that efficient is at least 94% power supply module, and what this power supply module adopted is the N+N Redundancy power supply.
Embodiment: the 220V civil power of general prior art is converted to+the 12V direct current by AC/DC, and+12V direct current is connected with the power supply copper bar; Each node of power taking end is directly at copper bar power taking+12V.
In the present invention, the 220V civil power is converted to+the 48V direct current by AC/DC, and+48V direct current is connected with the power supply copper bar; Each node of power taking end is directly at copper bar power taking+48V.
The contrast of two kinds of power supply modes is as follows, and wherein a is prior art, and b is the present invention:
That is:
Wherein,
Conduction loss for the electric power-feeding structure that adopts prior art;
Be power supply copper bar conduction voltage :+12V;
Can find out from above analysis result, under identical bearing power:
Adopt the conduction loss that electric power-feeding structure of the present invention can the decrease cabinet system, thereby be beneficial to the reduction system energy consumption.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
